Composition studies is a rapidly growing and constantly changing field. At present, however, graduate students new to the field and writing teachers who want to make new connections between theory and practice have little choice of current reference works that define key terms in composition studies and provide information about the scholars and researchers who have shaped and are shaping the discipline. This book supplies this information in an easily accessible format and places both scholars and terms in the context of the field's development. Included are alphabetically arranged entries for 108 individuals who have developed the field and 128 terms central to the discipline. The first part of the book provides entries for leaders in composition studies. Each entry identifies the areas in which the scholar has contributed most influentially to the field and provides both a chronological overview of the person's contributions and a bibliography of representative works. The second part includes entries for terms that are problematic both for newcomers and for those already familiar with the discipline. The entries for the terms show how the disciplinary context has shaped the ways in which they have been used. The entries also indicate how established thinkers in composition studies and other disciplines have explained or defined the terms, provide examples of the terms in context, and list scholars often associated with them. An appendix includes entries for scholars from other disciplines who have contributed to the field.
